Well Rehabilitation

Well Rehabilitation

Water wells require regular maintenance to ensure adequate water flow and continued drinking water safety. As a water well ages, the rate at which water may be pumped (commonly referred to as the well yield, flow or performance) tends to decrease, especially in wells that were not properly developed when first drilled. A drop or complete loss of water production from a well can sometimes occur even in relatively new wells due to a lowered water level from persistent drought or over-pumping of the well which can dewater the water-bearing zones. Major changes in any of the following well characteristics is an indication that your well or pump is in need of attention:

Decreased pumping rate

Decreased water level

Decreased specific capacity

Increased sand or sediment content in the water (cloudiness)

Decreased total well depth

The two most common methods to rehabilitate a water well are:

Chemicals to dissolve the incrusting materials from the well (Acidizing)

Physically cleaning the well

Physical methods include using a brush and percussion tool attached to a drilling rig, high pressure jetting, and well surging. The latter techniques all include injecting water (and sometimes chemicals) into the well under extreme pressure. Sometimes a combination of these methods are used depending upon the reason(s) for the decrease in well performance.
